The test specimen roof panels were then mounted inside the salt spray test chamber and subjected to 1,000 hours of salt spray at a chamber temperature range of 92-97 degrees F. The salt solution was prepared to 5 parts by mass of sodium chloride (salt) in 95 parts of water (a 5% salt solution). The solution pH remained in a neutral range of 6.5 to 7.2. Upon completion of the 1,000 hours salt spray …

Typically this test runs from 8 to 3,000 hours. Though as earlier mentioned, there are a variety of other corrosion tests, salt spray test is very standard. However, opinion is divided among experts about how closely it reflects real life conditions. Some experts, for instance, question how suitable the test is when it does not involve exposure to salt chemicals.

I'd at least expect 150-500 hours if you seriously expect that type of part life. The environment around the part also matters. If the part will see physical damage, heat, water, and/or salt, you may want to beef up your finish and your salt spray requirements.

72 hours of UV exposure; 72 hours of salt spray; 24 hours of freezing; After 25 weeks, (4,200 hours) the test panels are evaluated for corrosion. A number of research papers have presented a correlation coefficient of at least 0.71 for the cyclic nature of ISO 20340/ISO 12944-9, in which atmospheric conditions change.

In your report, state the specifications and what you observe when the test is over. If your customer specifications just say something like, "must pass 200-hours salt spray per ASTM B117," you don't have enough information and you need to get firm criteria from the customer.
